Mars 2020/

Over the past two decades, missions flown technology to benefit future robotic and human by NASA’s Exploration Program have . shown us that Mars was once different from the , dry it is today. Evidence Key Objectives discovered by landed and orbital missions point • Explore a geologically diverse landing site to wet conditions billions of ago. These environments lasted long enough to potentially • Assess ancient habitability support the development of microbial . • Seek signs of ancient life, particularly in special rocks known to preserve signs of life over time The /Perseverance rover is designed to better understand the of Mars and seek • Gather and soil samples that could be signs of ancient life. The mission will collect and returned to by a future NASA mission store a set of rock and soil samples that could be • Demonstrate technology for future robotic and returned to Earth in the future. It will also test new human exploration

Mission Timeline Key Hardware

• Launch in July-August 2020 from Cape Perseverance will carry seven instruments to Canaveral Air Force Station, conduct unprecedented and test new • Launching on a ULA 541 procured under technology on the Planet. They are: NASA’s • Mastcam-Z, an advanced camera system with • on Mars on , 2021 at the panoramic and stereoscopic imaging capability site of an ancient in a that once with the ability to zoom. The instrument also filled Crater will determine of the surface and assist with rover operations. The principal • Spend at least one Mars (two Earth years) investigator is James Bell, State exploring the landing site region University in Tempe. • SuperCam, an instrument that can provide imaging, Rover and Dimensions chemical composition analysis, and mineralogy at a distance. The principal investigator is Roger Wiens, Los Perseverance’s body and other major hardware (such as the Alamos National Laboratory, Los Alamos, New Mexico. cruise stage, descent stage, and /) build This instrument also has a significant contribution from the upon the success of NASA’s rover and include many Centre National d’Etudes Spatiales, Institut de Recherche heritage components. The car-sized Perseverance rover has en Astrophysique et Planétologie (CNES/IRAP), . roughly the same dimensions as Curiosity: it’s about 10 feet long (not including the arm), 9 feet wide, and 7 feet tall (about • Planetary Instrument for -ray Lithochemistry (PIXL), an 3 meters long, 2.7 meters wide, and 2.2 meters tall). But at X-ray spectrometer and high-resolution 2,260 pounds (1,025 kilograms), Perseverance is about 278 imager to map the fine-scale elemental composition of pounds (126 kilograms) heavier than Curiosity. materials. PIXL will provide capabilities that permit more detailed detection and analysis of chemical elements than ever before. The principal investigator is , NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, .

• Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals (SHERLOC), a spectrometer that will provide fine-scale imaging and uses an (UV) to map mineralogy and organic compounds. SHERLOC will be the first UV Raman spectrometer to fly to the surface of Mars and will provide complementary measurements with other instruments in the payload. SHERLOC includes a high-resolution color camera for microscopic imaging of Mars’ surface. The principal investigator is Luther Beegle, JPL. Technology

• The Mars In-Situ Resource Utilization Experiment Perseverance will also test new technology for future robotic (MOXIE), a technology demonstration that will produce and human missions to the . That includes oxygen from Martian atmospheric dioxide. If an autopilot for avoiding hazards called Terrain Relative successful, MOXIE’s technology could be used by future Navigation and a set of sensors for gathering data during the on Mars to burn fuel for returning landing (Mars Entry, Descent and Landing Instrumentation 2, to Earth. The principal investigator is Michael Hecht, or MEDLI2). A new autonomous navigation system will allow Massachusetts Institute of Technology, Cambridge, the rover to drive faster in challenging terrain. Massachusetts. As with Curiosity, Perseverance’s baseline power system • Mars Environmental Dynamics Analyzer (MEDA), a set of is a Multi-Mission Radioisotope Thermoelectric Generator sensors that will provide measurements of , (MMRTG) provided by the U.S. Department of Energy. It uses speed and direction, pressure, relative humidity, and the heat from the natural decay of -238 to generate size and shape. The principal investigator is Jose electricity.
